Then, the moving ends of the two second linear movement mechanisms 2 extend, driving the two moving plates 5 to move away from each other to open the clamping jaws 7. When the bottom of the clamping jaws 7 moves to both sides of the workpiece, the moving ends of the two second linear movement mechanisms 2 retract, and at this time, the two clamping jaws 7 move closer to each other to clamp the workpiece. It has the advantage of being convenient for clamping the workpiece.
